摘　　要：在推流式曝气池中 ,底物浓度沿程逐渐降低 ,而活性污泥浓度在曝气池前部会逐渐升高、在后部有可能会呈下降趋势。根据细菌在不同生长阶段的增殖动力学方程 ,可建立活性污泥及底物浓度的沿程计算模式 ,并可通过这一系列数学模式确定曝气池中各生长阶段的起讫点。The concentration of organic substance decreases with flow in plug flow aeration tank. The concentration of activated sludge increases in the fore part of the tank but it is possible that the concentration will decrease in the rear part of it. The mathematical models of activated sludge and organic substance with flow are deduced according to the equations of bacteria growth in various steps. The start points and end points of each step could be determined with the models.
